Owning your own home

Probably not.

Less landlords mean potentially more properties for homeowners, of which there is a shortage so that could be positive.
However, fewer private landlords (or replacement for those landlords leaving the market selling to homeowners) in the absence of social houses and rent mean that the demand for rental properties become even worse than it is now.
rapid increases in rental prices due to increased demand.
Any attempt to cap this will mean more landlords sell, reducing rental housing stock which further increases demand.

I know that a couple of family homes came up for rental near where I am where they had over 30 viewings booked.

Plenty of shit landlords out there who should be pushed out the market, but this might result in the crap landlords & HMO landlords who don’t spend money to look after the properties and their tenants being the only ones left with enough of a return to stay in the BTL market.
